able openings such as 1'7 in this base portion. This chamber extends short of the height of the compartment 15 and is desired to be slightly above the normal level 48 of the liquor contained in the compartment 15 when a boiling is desired but the liquid will be abovethe top of this chamber Vwhen circulation `is to be obtained ,without boiling. Within this chamber thereis provided a plurality of pipes 18 each of which lead upwardly from the pocket 19 supplied ,by conduit 20 l and thence downwardly as at 21 to a similar pocket 22 which is exhausted through pipe 23 to afford a means for supplying any` suitable vfluid-heating means, steam being used as a convenient supply for the purposes of this invention.

The conduits 18, 21 occupy a large portion of the space of the chamber 16 and consequently a comparatively small volume of liquor'is contained therein and will be quickly heated by contact with the large area of heating surface to cause a violent boil andy discharge of the liquorvby 4striking against a baille 'plate 24 Yand being dispersed Y throughv theopenings 25- into the liquor in the and -thus driven into the central chamber 16 to increase the heat andcirculating movement of the liquor therein. Thus the steam which is lformed from the liquor itself, is transferred back tothe liquor thereby eliminating any dilution thereof. 4The valve 27 vof course, will be closed until sufficient steam is generated to'permit this 'action to take place. l l The injector is of the usual type' with Venturi necks 29 and 30 and is connected to the liquor as at 31 for the liquor suction.' Whenever the steam, as above described is used, it is, of course necessary to seal the opening 32 in the neck 12 by ysuitable cover provided for that purpose.l How-,- ever, where'heatis not sufficient Vto form steam ra cover is lnot required.

In some cases, itis 'desired to more quickly circulatev the liquor and cause the large volume vof work and liquor toboil, as at the start of the operation, in which case steam from an outside source may be injected through the conduitr 33, shut off 'valve 34 and nozzle 35, which is similar to the-'nozzlev 29, directly into the liquor, in which case the liquor will be mixed more concentrated than is finallyv desiredv to counteract the dilution of-thesteam.l n n Y There are no metal moving parts in the operation of the kier constructed as above disclosed,

the circulation is caused by difference in density of the liquor when the level is above the heating chamber or by boiling the liquor and causing it to be thrown against the baille plate and permitting it to settle again through the cloth or work to be acted upon.' The heat supplied is entirely contained within the Work vcompartment of the kier. Radiating losses are reduced and yet the Work is protected from direct application with the heating pipes 18 and 21 by the tubular shell 40 which also serves to form a `chamber for setting up a circulationof the' liquor; and `further by the operating means being entirely'contained within the compartment a saving of floor space, electric motors, engines and pumps is accomplished, and the heating and circulating may be maintained without dilution of the liquor.

Further, the construction is such that globules of steam forming about the steam pipes 18 and 21 or any entrained air or gases in the liquor of thechamber are Yafforded aneasy path of rise orA escape. Likewise, any airor gases entrained in the goods acted upon may in asimilar manner escape upwardly to ythe space above the liquor, whereby a greater efficiency is obtained and as the circulation is of a milder degree, no channeling will be caused to prevent proper action of the liquor upon the work. y

The liquor is usually supplied through the conduit 36 at the vbottom of the kier and tends to cause the work 50 to rise, which is prevented by chains 37 shackled in one of the openings 38 in-the vangle irons 39 extending along the side of the cylinder 10. The chains are connected at their center to a' ring 44 which has a free movement along the chamber 16 and hold the work 50 below the level48v of'liquor therein.'

While we have described certain construction formsk Whichembody the principles or our in vention, it is obvious that other desired changes in arrangement, may be made withinv thespirit and the scope of the inventionas defined in the appended claims. L

5. A method of circulating treating liquor through work in a kier, including heating a central portion of the volume of the liquor to produce circulation of the treating liquor and to generate steam, and `injecting the generated steam into the central portion of the liquor to increase the flow velocity thereof.
